dcaron - C'est merveilleux!!!

Thank you for the write up, great work. I have a slow leak, turns out to be the O-Ring around the pump/tank.
The system works perfectly, except for the slow leak.
My input on this topic:
If your pumps work and you are still losing fluid, check the seal between tank & pump. Apparently the dealer sells the O-Rings separately, I will be going this week, fingers crossed!
I also found this nice photo DIY that is helpful, the guy repaired his pump, but you can buy them for under $10 online!
